Junho is 14 and his brother Chansung is 10 but acts like a little kid, hes always been that way. You see he was actually adopted by Junho’s parents when he was only 6 years old, he had been living at the orphanage since he was a kid, both his parents left him when they notice Chansung wasn’t like other children, he acted differently not that there was anything wrong with him far from it.. He was just different and his rich parents didn’t approve and thought he was a problem child.
